Wisconsin wild : Another petaloid male-sterile cytoplasm for carrot

Cytoplasmic diversity is a desirable attribute in the production of F1 hybrids. Even though most breeders agree with this concept, the vast majority of carrot (Daucus carota L.) hybrids produced in the United States are in one cytoplasm, i.e., the Cornell cytoplasm. To expand the diversity of cytoplasm for cultivated carrot, the U.S. Dept. of Agriculture announces the release of the Wisconsin Wild cytoplasm.
